A twice-daily regimen of hyaluronic acid serum and peptide cream improved skin texture in 79% of women with sun-damaged skin after 12 weeks, with no adverse effects.

What the researchers found
A 12-week skincare regimen combining a hyaluronic acid serum and a peptide-rich cream improved the appearance of sun-damaged skin on both face and neck. On the face, 79% of subjects showed improved skin texture, 50% showed reduced lines and wrinkles, and 44% showed improved skin tone. On the neck, improvements were seen in texture (68%), tone (48%), and lines/wrinkles (36%).
No adverse events were reported. All 17 subjects reported overall skin improvement and smoother-feeling skin. Eighty-eight percent said their skin looked more radiant, and 82% said it looked firmer.
Why it matters
Peptide-containing skincare products are increasingly popular, but many lack clinical testing. This study provides clinical data on a specific HA + peptide combination, showing measurable improvements in photodamaged skin over 12 weeks with no adverse effects. However, the absence of a placebo control limits the ability to attribute improvements specifically to the active ingredients.
The numbers in context
n=17 · 12 weeks · Face: 79% texture improvement, 50% wrinkle improvement, 44% tone improvement · Neck: 68% texture, 48% tone, 36% wrinkles · 0 adverse events · 88% reported more radiant skin
How the study worked
Open-label, single-arm study with 17 female subjects (mean age 52) with mild to moderate photodamage. Participants applied a hyaluronic acid serum and peptide-rich cream twice daily for 12 weeks. Changes in skin texture, tone, and lines/wrinkles were assessed on a 6-point grading scale. Subject satisfaction was surveyed and adverse events were tracked throughout.
Who was studied

What this study cannot tell us
Very small sample size (n=17) with no control group, no blinding, and no placebo comparison — meaning improvements could be due to the moisturizing effect of any cream, the placebo effect, or natural variation. Only female participants were included. The specific peptides in the cream are not identified in the abstract, making it impossible to attribute results to particular peptide ingredients. The subjective satisfaction measures are prone to bias.
How to read the evidence
This is a small, open-label study with no control group, no blinding, and subjective outcome measures. While it documents improvements, the study design cannot establish that the peptide ingredients specifically caused those improvements, placing it at a low evidence level.
When this study was published
Published in 2022, this study reflects current cosmetic formulation approaches. The lack of a control group remains the study's primary weakness regardless of publication date.
The bigger picture
The cosmetic peptide market is growing rapidly, but rigorous clinical evidence for many products remains thin. This study adds a data point for peptide-containing skincare, though the absence of a control group means it cannot distinguish peptide-specific effects from general moisturization. Better-designed studies with placebo controls are needed to advance the field.
Questions still open
- Would a placebo-controlled version of this study show similar improvements from any moisturizing cream?
- Which specific peptides were in the cream, and do they have independent evidence of skin benefit?
- How do these results compare to retinoid-based treatments for photodamaged skin?
Common questions
Do peptide creams actually work for wrinkles?
Is hyaluronic acid better with peptides?
